II. Technology and Patent(s)-in-Suit Analysis
U.S. Patent No. 9,729,658 - “SYSTEM FOR MANAGING WEB-BASED CONTENT DATA AND APPLICATIONS”
- Patent Identification: U.S. Patent No. 9,729,658, “SYSTEM FOR MANAGING WEB-BASED CONTENT DATA AND APPLICATIONS,” issued August 8, 2017.
The Invention Explained
- Problem Addressed: The patent’s background section describes prior art systems as deficient for requiring users to perform multiple log-ins to access content from different sources and for lacking a single interface to manage them (’658 Patent, col. 1:53-58). It also identifies limitations in existing "scrolling software," which either relied on content stored locally on a mobile device or used "plug-in and play" software that was not integrated with a web application to handle real-time data from multiple sources (’658 Patent, col. 2:2-29).
- The Patented Solution: The invention is a cloud-based architecture where a central "master server" acts as a single access point, aggregating content data and applications from multiple different sources in real time (’658 Patent, col. 2:30-41). This content is presented on a "dynamic master web-page" where a user can navigate through the different content streams using a "slide tool" without needing a plugin (’658 Patent, col. 2:60-65). The system is also described as including a "remote tool box" for an administrator to manage how content is organized and displayed, and to collect analytics (’658 Patent, col. 3:12-24).
- Technical Importance: This approach aimed to provide a seamless, smartphone-like "swipe" navigation experience within a standard web browser for content that was being streamed live from disparate sources, which the complaint frames as an "unconventional" and "innovative solution" for its time (Compl. ¶¶ 25, 27).
Key Claims at a Glance
- The complaint asserts infringement of at least independent claim 1 (Compl. ¶42).
- Essential elements of claim 1 include:
- A cloud-based computer system comprising a master server accessible over the internet.
- A master application on the server that organizes content streamed in real time from multiple sources onto a master web-page.
- The master application programs a processor on a remote computer to execute a "slide tool program" for scrolling or paging through the content.
- A "remote tool box feature application" allowing a user to write, select, or delete code to control how subsets of content are displayed, with the master server collecting analytics to target information to the user.
- The complaint does not explicitly reserve the right to assert dependent claims.
U.S. Patent No. 10,334,068 - “SYSTEM FOR MANAGING WEB-BASED SWIPE MODULE TOOL AND SOFTWARE FOR SCROLLING AND PAGING THROUGH CONTENT DATA AND APPLICATIONS”
- Patent Identification: U.S. Patent No. 10,334,068, “SYSTEM FOR MANAGING WEB-BASED SWIPE MODULE TOOL AND SOFTWARE FOR SCROLLING AND PAGING THROUGH CONTENT DATA AND APPLICATIONS,” issued June 25, 2019.
The Invention Explained
- Problem Addressed: As a continuation of the application for the ’658 Patent, the ’068 Patent addresses the same technical problems: the inability of prior systems to manage and navigate real-time content from multiple web sources through a single, integrated, plugin-free interface (’068 Patent, col. 1:59-66; col. 2:24-37).
- The Patented Solution: The patented solution is functionally identical to that described in the ’658 Patent. It discloses a cloud-based system with a master server that aggregates pre-selected content sources, presents them on a unified master web-page, and provides a "slide tool" for navigation (’068 Patent, Abstract). The system architecture, as illustrated in Figure 1, depicts multiple content source servers (101, 103) feeding into a master server (105) that communicates with a remote user device (111) (’068 Patent, Fig. 1).
- Technical Importance: The technology is presented as a "next-generation software platform" that could integrate with customers' existing systems to enhance web delivery of information and entertainment (Compl. ¶25, Ex. 5).
Key Claims at a Glance
- The complaint asserts infringement of at least independent claim 1 (Compl. ¶45).
- Essential elements of claim 1 include:
- A cloud-based computer system with a master server accessible over the internet.
- A master application on the server organizing content from multiple "pre-selected" sources, streamed in real time to a master web-page.
- The master application programs a remote device's processor to execute a "slide tool program" for scrolling through the content.
- A "remote tool box feature application" that allows code to be written, selected, or deleted to control content display, with the server collecting analytics to target information to the user.
- The complaint does not explicitly reserve the right to assert dependent claims.
III. The Accused Instrumentality
Product Identification
- The accused instrumentality is the "Twitch Video System," which includes the services and features accessible at
https://www.twitch.tv/, particularly its "live video carousels" (Compl. ¶¶ 5, 29, 36).
Functionality and Market Context
- The complaint describes the Twitch system as a cloud-based platform that delivers live video streams from individual broadcasters to viewers (Compl. ¶29). Servers are alleged to ingest live media from these numerous, independent broadcasters simultaneously in real time, using protocols such as RTMP (Compl. ¶¶ 30, 33).
- This live content is organized on Twitch's webpage into "carousels," which viewers can horizontally page or scroll through to browse different live streams (Compl. ¶¶ 30, 31). The complaint includes a screenshot of the Twitch user interface showing a live stream with left and right arrows for navigating a carousel (Compl. ¶31, Screenshot).
- The system is also alleged to include a "remote tool box" that allows Twitch and its users (streamers) to control how content is organized and displayed (Compl. ¶35). Examples provided include a feature for adding descriptive "Tags" to a stream and a "Suggested Channels" feature for promoting other content (Compl. ¶¶ 37, 38).
- The complaint alleges Twitch is a wholly owned subsidiary of Amazon.com and part of Amazon Web Services (AWS), suggesting a large scale of operation (Compl. ¶¶ 39, 40).

- Identified Points of Contention:
- Scope Questions: A central question may be whether Twitch's standard web-based carousel, implemented with browser-side code (e.g., HTML, JavaScript), meets the definition of a "slide tool program" that the patent describes as being enabled by a "down load of software on to the remote computing device" (’658 Patent, col. 7:1-4). The defense may argue this limitation requires a distinct software installation beyond typical browser operation.
- Technical Questions: The infringement allegation for the "remote tool box" limitation hinges on whether features like adding text-based "Tags" or selecting channels for a list constitutes an application that "allows the user to write code, select code or delete code" as required by the claims. The court may need to determine if entering text in a form field or making UI selections is technically equivalent to the claimed "writing" or "selecting" of "code."
V. Key Claim Terms for Construction
The Term: "slide tool program"
- Context and Importance: This term is fundamental to the infringement case. Whether Twitch's carousels infringe will depend heavily on the construction of this term. Practitioners may focus on this term because the patent's description of a "down load of software" to enable the tool could be interpreted as requiring more than the standard delivery of executable code to a web browser.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The specification broadly describes the tool's function as something that "allows a user to scroll or page through the content data" (’658 Patent, col. 2:61-63), which could support an argument that any UI element performing this function qualifies.
- Evidence for a Narrower Interpretation: The specification states that "the master application 107 initiates a down load of software on to the remote computing device 111 that enables a the slide tool" (’658 Patent, col. 7:1-4). This language may support a narrower construction requiring a discrete, downloadable application or plugin, distinct from the code that renders the main webpage.
The Term: "remote tool box feature application that allows the user to write code, select code or delete code"
- Context and Importance: This limitation is highly specific. The viability of the infringement allegation against Twitch's "Tags" and "Suggested Channels" features depends on them meeting this definition. The term "write code" is particularly restrictive and will likely be a point of significant dispute.
- Intrinsic Evidence for Interpretation:
- Evidence for a Broader Interpretation: The patent does not appear to explicitly define "code." A plaintiff might argue that entering text tags that are then processed by the system is a form of "selecting code" or providing input that functions as code.
- Evidence for a Narrower Interpretation: The plain and ordinary meaning of "write code" suggests a user is typing programming commands (e.g., in a scripting language). Entering text into a metadata field or selecting from a pre-defined list of channels may be argued to fall outside this meaning. The complaint's own allegation that users "write code, enter settings, and/or select icons" (Compl. ¶35) suggests a distinction between these actions that could be used to argue for a narrower construction of "write code."
VI. Other Allegations
- Indirect Infringement: The complaint alleges inducement of infringement. The factual basis for this claim is that Twitch allegedly provides instructions and documentation to its users (streamers) that teach them how to use features like "Tags" and "Suggested Channels" in an infringing manner (Compl. ¶¶ 37-38). The complaint includes screenshots of these instructions (Compl. Ex. 9, Ex. 11).
- Willful Infringement: The complaint does not contain a specific count for willful infringement or allege that Defendant had pre- or post-suit knowledge of the patents. It does, however, request in its prayer for relief an order declaring the case "exceptional" and awarding attorneys' fees pursuant to 35 U.S.C. § 285 (Compl. p. 13).
VII. Analyst’s Conclusion: Key Questions for the Case
- A core issue will be one of technical and definitional scope: Can the patent term "slide tool program," which the specification links to a "down load of software," be construed to read on a standard, browser-based web carousel? The outcome may depend on whether the court views modern web architecture as inherently practicing the patent's method or as being fundamentally different from the "downloaded" tool described.
- A second central question will be evidentiary and functional: Does the act of a user entering text into a "Tags" field or selecting a channel for a "Suggested Channels" list constitute "allow[ing] the user to write code, select code or delete code" as required by the claims? The case may turn on what evidence Plaintiff provides to demonstrate that these user interface functions are technically equivalent to the specific, code-manipulating actions recited in the patent.
